IMPROVEMENT IN ROTARY STEAM=ENG|NES.

Specification forming part of Letters Patent No. 123,320, dated January30, 1872.

To all whom it may concern:

Be it known that I, GUSTAVUS R. WINK- LER, of W'illiamsport, in thecounty of Lycoming and State of Pennsylvania, have invented certain newand useful Improvements in Rotary Steam-Engines; and do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing making a part of thisspecification, in which Figure 1 is a top-plan view of the device; Fig.2, an end elevation of the same; Fig. 3, a plan view of the shell withone of the ends removed; Fig. 4, a view of the hollow shaft, showing thesteam-ports; Fig. 5, a separate view of the piston; and Fig. (i, avertical section of one of the ends of the shell, showing aneccentric-wheel in position.

Like letters of like kinds denote corresponding parts in each figure.

The nature of my invention relates to 1'0- tary steam-engines; and itconsists in the peculiar construction and arrangement of the piston; inthe combination with such piston of a hollow shaft provided withsteam-ports; in the means employed for revolving the shell and the shafttogether; and in the combination of the severaloper tive parts, all asmore fully hereinafter described.

In the drawing, A represents a proper frame for the support of theengine, upon wnich is journaled the shaft B, which is hollow from end toend, with a central enlargement, B, which is divided in the centervertically by a partition, (I, on each side of which are the steam-ports0, arranged as shown in Fig. 4. This shaft passes centrally through acircular shell, I), to which it is firmly secured by the pins a,composed of end pieces I) b and a central periphery, a, properly securedtogether. Upon each of these ends, and upon the outsides of them, is aring, E, surrounding the shaft B in such a position that the centralpoint of said ring is at a little distance from said shaft, and in therevolution of said shaft turns eccentrically around it. Embracing theserings just named are guides F, secured to the frame A, in which guidesthe rings revolve, as before named. Three pins, (1, pass through theserings and through three wheels, G, near the periphery of each of them,and serve as spindles, upon which each of said wheels revolveseccentrically in suitable bed'swithin each of the end pieces I) b of theshell D. These same pins (1 enter into the ends of the scroll-piston H,of the form particularly shown in Fig. 5, filling up the space betweenthe interior. walls of the shell, by means whereof the motion of therings E is communicated to said piston, which revolves in precisely thesame orbit as that of said rings. This piston has an opening, 0, betweenits endsf, as shown in the fig ure just alluded to. A partition, I,filling-the interior of the shell, extends from the enlargement B of theshaft through the opening 6 of the piston to the opposite inner wall ofthe shell, being firmly secured at each end.

In the operation of my device the live steam enters the hollow shaft Bat one end, passes out of one of the ports (J, strikes against thepartition I, and fills the space between the piston on that side and theshaft. By its impulse the shell and shaft are rotated, the piston in itseccentric movement closing the opening between its end f and the side ofthe partition upon which the steam has entered, and opening the spacebetween its other end and the opposite side of the partition, by meansof which the steam is exhausted in each revolution of the shell, throughthe other port, and out of the other end of the shaft, which motion iscontinued as long as steam is admitted. To reverse the rotation of theshell live steam is admitted into the opposite end of the shaft and theshell is rotated in the opposite direction in the manner just described.

Having thus described my device and its mode of operation, what I claimas new there in and my invention, is-

l. The scroll-shaped piston H, constructed, arranged, and operatedsubstantially as set forth.

2. The combination of the shell D and hollow shaft B, secured togetherand turning simultaneously, substantially as set forth.

3. The combination of the hollow shaft B, the scroll-piston H, and thepartition I, constructed and arranged substantially as de scribed andshown.

4. In combination with the shell D, the shaft B, rings E, guides F,wheels G, piston H, and partition I, constructed and arrangedsubstantiall y as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this29th day of November, 1871.

GUSTAVUS B. WINKLER.
